agreed with everything you've said but why is it in migrating towards this Andromeda Windows OS, you have to drop W10M completely? dropping in markets that you had many loyal and even newly loved users, after release of 950/XL Microsoft should've used all efforts into making W10M polished and creating fully unique experiences not putting all exclusives on other platforms. I've converted about 100 people to W10M and most are frustrated but are so in love with the UI in comparison to Google and iOS.
The thing with most engineers is that in the simplest sense they approach things two ways - replace a faulty part or cut it out completely.
Then when you throw in reliance on analytics and telemetry you have a mess in the making because numbers only tell you on portion of the picture not the complete picture. You cannot quantify what makes some one smile, I know this is probably been discussed ad nauseam but the photo hub was redesigned based on telemetry. Instead of seeing a panaroma of your favourite moments, you see a grid of photos. Because they saw people were going to the albums and camera roll soon after opening the photohub (Joe Belfiore mentioned that during one of the build events to reiterate a point on efficiency). What they cannot see is a person's smile when you look at a priceless moment and that can be difference between a good day or bad in the office for someone - that feeling cannot be quantified.
Plus add in the mix the bubble that most of Microsoft appear to be in, for example the marquee features of bing in Wp7 and Wp8 never made it out of the US. It's taken several years to bring bing rewards to other markets, had they done this sooner than they would have a way larger market share.
So going back to the first point, we had an amazing feature in rooms and then replaced by groupme which hardly anyone uses. Messaging everywhere gutted for the favour of skype, speaking of skype it was apparent that office politics was directing the roadmap.
Some engineers do not understand the concept of transitional phases and when you have majority of them... you get the haphazard pathway that we have seen on countless occassions and still seeing - combined with a risk averse leadership.... Of course office politics, stack ranking and inter-department resource competitions didn't help either (however, fortunately that appears to be slowly fading). I would say because of that we will never anything akin to the Zune client, where it would sync your music and playlist via WiFi whilst your phone was charging or the ill fated live lockscreen or LED notifications etc.
Windows phone 7 -> 8 and WM10 had alot of potential, still does but that going forward that lays with UWP... in regards to the actual mobile code that is now part of the Windows Core. The Wp UX is now used for the surface hub. The windows mpbile platform had so much potential but it was marred by so many factors, I could get into detail but I'd end up typing up a million page book
Never the less I still have faith, not in Satya Nadella but in the people who are heading the major departments suchas Panos Panay. Because you know he would never consider showcasing a competing platform alongside the hardware he and his team have painstakingly + loving designed.
Case in point when he was talking about his flow during the Future Decoded keynote, he talked about his day and what he did to reiterate the point / give more visceral information he could have taken out a competitors smartphone like some of his colleagues but he did not. He also uses the Surface Mini as his personal note taking device. That to me speaks volumes, you can tell a lot about a person from their mannerisms and body language.
Another example, the brief show case of the Lumia 950 and 950XL - it was so brief...
I personally wouldn't stand behind such a poorly designed product... the launch issues really indicated how much testing went in. Then again that's what happens when you fire all your dedicated programmatic testers. I'm not denigrating the people who designed the product but the software did not live upto flagship expectations and then compare the aesthetics of the devices to other products in that category... it's just meh at best (creaking back plates on a £500 product is a huge fail).
Although I prefer the design as a minimalist thus have no qualms about it, however it's not a design that screams premium. They should have shipped one of the premium Mozo back cover with the devices, then use that to launch the accessories for lumia line up.
I am hoping the Microsoft store launch in the UK will be a mark of postive change in the direction of consumers.
